Delivering an explosive charge of nutrients, minerals, and carbohydrates, Mills C4 stimulates a profound increase in bloom and the production of sugars and essential oils. This powerful yet complex fertiliser is rich in the potassium and phosphorus your plants require to maximise fruit and flower density. For rapid bloom acceleration and uninterrupted progress C4 provides macro and micro nutrients in a readily available form for immediate uptake.

C4’s nutritional content is complemented by an abundant supply of beneficial microorganisms. These produce yet more food by breaking down naturally occurring dead organic matter in the root zone. Bio-stimulants are deployed to ramp up sugar and oil output, meaning your crops will be denser, harder, and heavier than ever before.
